B. 3., OF COLOGNE-MERHEIM, GERMANY APPARATUSFOR TREATING SPUN CAKES OF ARTIFICIAL SILK OR THE LIKE Applicationfiled. April 23, 1931; Serial No. 532,226, and in Germany May I, 1930.

The processes hitherto known for washing and subsequently treating(desulphurizing, bleaching, sizing, dyeing, etc.) spun cakes ofartificial silk and cake-like coils of thread generally requirecomplicated apparatus, which permit only of a comparatively uneconomicalmode of working on a mass production scale or else they operate so as tochange the shape of the cake thus interfering with the further workingup thereof.

Now the present invention enables spun cakes or the like to be subjectedto subsequent treatment mechanically and in great numbers in a simpleway without any change in their shape. This is achieved preferably bypresenting the material to be treated to the various liquids insuccession in a continuous process.

In the apparatus of the present invention the spun cakes or the like arearranged on perforated or slotted carriers each spun cake beingpreferably mounted on a separate carrier. A nummr of such carriers ordrums are threaded on to a discharge pipe for the liquid with which theyare to be treated, for example, a perforated or slotted discharge pipe.

Now according to this invention, in order to increase the capacity ofthe apparatus, a plurality,'of pipes with spun cakes or the likearranged thereon are provided on the underside of a container which isdesigned to hold the liquid usedfor treating the cakes and which is fedby suitably disposed liquid supply pipes. A number of such containersare arranged in series and they may be conveyed in succession by atransporting device to the various points where the 'diiferent liquidsfor treating the cakes are supplied. Liquid caught in drainingreceptacles after being used to treat the coils of thread or spun cakesmay be returned to the containers which carry the cakes. If necessary apurifying apparatus may be interposed in the return path of such liquid.

Further features of the invention will be apparent 'on reference to theaccompanying drawings and the following description in which the newapparatus will be more fully explained.

Fig. 1 is a diagrammatic view of apparatus according to the presentinvention.

- Fig. 2is a vertical section through the apparatus shown in Fig.1.

Fig. 3 shows partly in section and partly in elevation, a liquiddischarge pipe with the spun cakes mounted thereon, oneabove another. vFig. 4 shows diagrammatically another way of constructing a pipe fordischarging the treating liquid and carrying the spun cakes. if

Fig. 5 shows an enlarged cross-section taken on the plane of the line 55of Fig. 4.

The cakes 1 are placed on perforated or slotted sleeves or drum-likecarriers 2 which are pushed, one after another, on to perforated pipes 3(see Fig. 3) or on to rods 4 of star-shaped cross section (see Fig. 4)and are fixed by wing nuts 5. The pipes 3 are perforated and theprofiled rods 4 are provided with slots 6 for the liquid to flowthrough.

The drum-like carriers may be of smaller diameter than the spun cakesand slightly greater in height than such cakes so as to afi'ord room forsuch cakes to expand both axially and radially and for the layers ofthread to loosen. The pipes 3 and the passages formed'between theprofiled rods 4 and the drums 2; communicate with the boxes 7 to whichthe particular liquid used for treating the cakes is sup lied throughfeed pipes 80:, 8b. The boxes have recesses 9 at. the top, which act asoverflows for the liquid supplied. The feed pipes 8a, 8b carry at theiroutlet ends filter bags 10a, 10b which also prevent the liquid fromspurting. As the discharge pipes 3 or 4 are closed at their lower endsthe liquid issuing from said pipes flows into the interior parts of thecakes 2 and through the layers of thread comprised in'such cakes intothe receptacles 11a, 11b, placed underneath for catching it. In order tosubject the cakes successively to the several washing treatments theboxes 7 with the cakes arranged beneath them are mounted on transporterchains. 12, which worked by driving gear 13 tensioned by ajockey roller14, bring the boxes'at suitable intervals (I of.

time, preferably with a pause for draining 11 inclined boards 16 may bearrange t e liquid which drops oil the cakes to the correspondingdraining vessel. The liquids used for treating the cakes are preferablypumped back in known manner, by the ump 17 out of the draining vessels11 into the oxes 7 On both sides of the machine and above thereceptacles 11 for catching the liquid are arranged walls 18, whichprevent the liquid used for treating the cakes from spraying outsideways and so protect the conveying mechanism.

- while charging with frame 20 as b . are obtained by To charge theapparatus with the cakes coming from thespinning machine there isprovided at one end of the machine, in front of the reversing roller 19of the trans orter chain, a frame 20 (only just indicated in thedrawing) on which the boxes 7 are placed they are pushed on to thetransporter chain. or thispurpose recessesj2lare provided in thesupports 15 on the boxes and the slide rails o the frame 20 engage inthese recesses. At the other end of the machine a similar is providedfor the removal of the oxes.

The boxes 7 with the cakes attachedthereto may, in some cases be movedby hand along suitable rails without using a transporter chain.

In addition to the treatment of cakes which the centrifu al process, theapparatus is equally suitable for washing and subsequently treatingcoils of threadwhich are spun on to spools on spooling machines andsubsequentlydrawn oif from such spools.
